SetPropertiesRule
public class SetPropertiesRule extends Rule (Code)

Rule implementation that sets properties on the object at the top of the stack, based on attributes with corresponding names.

This rule supports custom mapping of attribute names to property names. The default mapping for particular attributes can be overridden by using SetPropertiesRule.SetPropertiesRule(String[] attributeNames,String[] propertyNames) . This allows attributes to be mapped to properties with different names. Certain attributes can also be marked to be ignored.




Constructor Summary
public  SetPropertiesRule(Digester digester)
     Default constructor sets only the the associated Digester.
public  SetPropertiesRule()
     Base constructor.
public  SetPropertiesRule(String attributeName, String propertyName)
    
public  SetPropertiesRule(String[] attributeNames, String[] propertyNames)
    

Constructor allows attribute->property mapping to be overriden.

Two arrays are passed in.


Method Summary
public  voidaddAlias(String attributeName, String propertyName)
    

Add an additional attribute name to property name mapping.

public  voidbegin(Attributes attributes)
     Process the beginning of this element.
public  StringtoString()
     Render a printable version of this Rule.


Constructor Detail
SetPropertiesRule
public SetPropertiesRule(Digester digester)(Code)
Default constructor sets only the the associated Digester.
Parameters:
  digester - The digester with which this rule is associatedDigester.addRuleSetPropertiesRule.SetPropertiesRule()



SetPropertiesRule
public SetPropertiesRule()(Code)
Base constructor.



SetPropertiesRule
public SetPropertiesRule(String attributeName, String propertyName)(Code)

Convenience constructor overrides the mapping for just one property.

For details about how this works, see SetPropertiesRule.SetPropertiesRule(String[] attributeNames,String[] propertyNames) .


Parameters:
  attributeName - map this attribute
Parameters:
  propertyName - to a property with this name



SetPropertiesRule
public SetPropertiesRule(String[] attributeNames, String[] propertyNames)(Code)

Constructor allows attribute->property mapping to be overriden.

Two arrays are passed in. One contains the attribute names and the other the property names. The attribute name / property name pairs are match by position In order words, the first string in the attribute name list matches to the first string in the property name list and so on.

If a property name is null or the attribute name has no matching property name, then this indicates that the attibute should be ignored.

Example One

The following constructs a rule that maps the alt-city attribute to the city property and the alt-state to the state property. All other attributes are mapped as usual using exact name matching.

 SetPropertiesRule(
 new String[] {"alt-city", "alt-state"}, 
 new String[] {"city", "state"});
 
Example Two

The following constructs a rule that maps the class attribute to the className property. The attribute ignore-me is not mapped. All other attributes are mapped as usual using exact name matching.

 SetPropertiesRule(
 new String[] {"class", "ignore-me"}, 
 new String[] {"className"});
 

Parameters:
  attributeNames - names of attributes to map
Parameters:
  propertyNames - names of properties mapped to




Method Detail
addAlias
public void addAlias(String attributeName, String propertyName)(Code)

Add an additional attribute name to property name mapping. This is intended to be used from the xml rules.




begin
public void begin(Attributes attributes) throws Exception(Code)
Process the beginning of this element.
Parameters:
  attributes - The attribute list of this element



toString
public String toString()(Code)
Render a printable version of this Rule.
